Finely chop sausage, onion, and carrot.
Beat eggs in a bowl and season with salt.
Mix the chopped sausage and vegetables into the egg mixture.
Add oil to a pan and pour a little egg mixture over low heat.
When the egg is half-cooked, roll it and move it to one side.
Gradually add the remaining egg mixture, rolling as it cooks.
Once golden brown, let it cool and slice into bite-sized pieces.
